How to obtain the variable latent heat rate from the wrf output file ?

Failure of conda activate and init tcsh

In preparation of the tutorial, I tried to activate conda via: conda activate wp_env .

Got error msg:
CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
To initialize your shell, run
$ conda init <SHELL_NAME>

Tried to init shell via: conda init tcsh .
Error output received per the attached file.
"An unexpected error has occurred."

Is something missing? What to do?
I couldn't run the jupyter notebook, as suggested in the e-mail about the tutorial.

Thanks.

assign lon on x-axis

I used vertcross to get a longitude-pressure cross section of vertical wind.

Set the start and end points at the specific latitude (28.718N)

start_point = CoordPair(lat=28.718, lon=76)
end_point = CoordPair(lat=28.718, lon=78)

w_cross = vertcross(w, z, wrfin=file, start_point=start_point,
end_point=end_point, latlon=True, meta=True)

After that I put height labels on y-axis using the following code:

Set the y-ticks to use height labels.

vert_vals = to_np(w_cross.coords["vertical"])
v_ticks = np.arange(vert_vals.shape[0])
ax.set_yticks(v_ticks[::20])
ax.set_yticklabels(vert_vals[::20], fontsize=13

Now I want to put lon labels on x-axis but the w_cross has coords vertical and xy_loc and xy_loc is a CoordPair of lat and lon values.

How to extract lon out of this coordpair and put it on the x-axis?

Thanks in advance for your help.

asign lon on x-axis

coord_pairs = to_np(w_cross.coords["xy_loc"])
x_ticks = np.arange(coord_pairs.shape[0])
x_labels = [pair.latlon_str() for pair in to_np(coord_pairs)]
thin = [int(x/6.) for x in x_ticks.shape] # Only keeping ~5 horizontal ticks
ax.set_xticks(x_ticks[1::thin[0]])
ax.set_xticklabels(x_labels[::thin[0]], rotation=45, fontsize=8)

I tried this, but it puts both lat and lon on x-axis. How can I put only lon on x-axis ?
